Features

• This product function as level shift transceiver that change VCCA input level to VCCB output level, VCCB input level to VCCA output level by providing different supply voltages to VCCA and VCCB .
• This product is able to the power management : Turn on and off the supply on VCCB side with providing the supply of VCCA . (Enable input (G) : High level)

For power management system (1) VCCA V CCB HD151015 V systemCCBV systemCCA Be able to set up variable power supply voltage from 2 V to 6 V Be able to set up variable power supply voltage from 2 V to 6 V Be able to turn on and off Note: HD151015 is also used for power management system. We show some Examples. 1. For VCCA side Be able to switch fast mode (VCCA = 5 V) and power save mode (VCCA = 3 V) 2. For VCCB side Be able to switch normal mode (VCCB = 5 V) and suspend mode (VCCB = 0 V) 3. For both side Be able to switch fast mode (VCCA = 5 V) and power save mode (VCCA = 3 V) (When VCCA = VCCB , in this case, please switch VCCA and VCCB simulteneously.) For power management system (2) (Common bus line in different power system) V systemCCB HD151015 HD151015 X "H" 'V systemCCB VCCB = 0 V VCCB = 0 V "H" i V systemCCA *1 *2 HD151015 uses conventional CMOS input circuit. So, you have to care of designing in case of common bus line in different power block. We show one example. In this case, if VCCB become turn off, current flows from bus line to VCCB . (refer to *1) This is cause of malfunction. In order to prevent this problem, I recommend using this device for interface to each power block. (refer to *2)

[Cautions on using] Please use this IC on condition of VCCA usually ON, because if you use it on condition of VCCA being OFF, V CCB being ON, it will be troubled.
